OF PENNSYLVANIA sLAsi nR Diana Application filed October 22, 1928 Serial No. 314,107.

The object of invention is to provide stantially longitudinally of thethrea'ds; and. the thread supporting means isso arranged that the Warp threads alternately move in; the same general direction as the direction of and then in an opposite Y direction to the direction of movement of-the air. I

In this manner lateral strain on thethreads is reduced to a. minimum and tangling or tapping of adjacently positioned threads of the warp is obviated, and the air is more efiectivelyforced into the fibresof the threads to quickly drive the moisture; out. of the threads. l Another feature of the invention is, the arranging of the thread guides insuch a manner tha't'the GJIGCUOD of movementeofjthe' threads relative to the direction of movement of the air is changed at short intervals and that these guides areso arrangedthat the threads, while movinginthe same general direction or in an opposite direction-tothe travel of the air currents, cross theaircurrents ata slight angle, in order that practically all the air circulating inthef drying chamber will be brought into contact ,With the threads.

Making the respective alternating runs of the warp short permits the drier to be made more'compact for a given capacity and eliminatesthe traveling of'the air any great d s,- tance from its source of heatat any t1me, -thus the air can bemaintained at a more uniform" temperature. Y

= Another featureof the invention isthe pro- "vision of a fresh air'inlet'and an outleti for moist air, so arranged that like am'ountsof I Fig. at isa transverse air pass through the inlet and outlet simul- I taneously. I

Another feat-ure'is t e placing of the air outlet at the yarn-receiving end of the ap paratus and the airinlet at the yarn-discharge end of. the apparatus and so arranging the warpguidesthat the yarn in leaving the apparatus will pass through the incoming fresh air-,whereby leavingthe drier;

Referring to the accompanying drawings: Fig. l is a side elevation ofthe drier; Figs-:2 is a plan view;

Theo-machine comprises a su table open framework consisting of upright posts 1, Ion

gitudinal stringers 2, and transverse stringere-3. Suitable panels 4 are secured to the frame to form the casingof the machine.

.Theinte'rior of the casingis dividedint-o a drying chamber-1(),= which is sub-divided into compartments 10 and 10 by a trans: versely extending vertical partition l1,'and' a heating chamber 12 which is separated from the drying compartment 1O by a horizontal partition l3, which extends transversely of the casing'and from the central partition 11 to the warp-receiving end A of the casing. Heating coils 15 0f any suitable character are positioned above the compartment 10 of the-dryingchamber 10. Adjacent the warp-delivery end B, the casing is provided with a vertical partition 14 which extends from the roof of the. casing it is properly cooled before i to a'point' adjacent the floor thereof, as shown 1 The partition 1 1 extends-from the horizontalpartition 13to a point adjacent the floor of the-casing,providing communication between the compartments 10 and 10 'of the drying chamber 10 through the opening 16.

' The partitionl l forms at the -warpd'ischarging endB of the casinga fresh air opening series of guides, and then B of the casing.

conduit 17 which communicates through the opening 18 with the compartment of the drying chamber 10.

An air inlet 19 is formed in the roof of the casing and communicates with the fresh air conduit 17 the passage of air to the said conduitbeing regulated by a damper 20.

In the opposite end of the roof of the casing'is a'moist air outlet 21 which communicates twith the end of the heating chamber 12, at the most distant point from the heating coils 15. The passage of air through the outlet 12 is regulated by a damper 22'.

r In the horizontal partition 13 is a suitable 2st in which is rotatablymounted a fan 25 by means of which the air in thecasing is circulated in the general direction indicated by the arrows as, Fig. 3. g

A transverse beam 26 supports a bearing '27 in which one end of the shaft 28 is rotatably mountec. The fan 25 is secured to the shaft 28 adjacent the beam 26. The upper end of the shaft 28 is rotatably mounted in a bearing 29 carried by a transverse beam 30, a pulley 31 being secured to the shaft 28 adjacent the upper end of the bearing 29, by means of which thefan 25is rotated.

The bearing 2'? is set in a well 32 depending from the roof of the casing, the well comprising four angularly disposed walls 33 secured at one end to the roof of the casing and at the opposite end to the beam 26.

The warp threads Z enter the end A of the casing through a transversely extending slot 46, passing around rotary guide ll, from which the warp passes upwardly over the first rotary guide 12 of an upper series of guides, thence downwardly and under and around the first rotary guide48 of a lower alternately over and under the remaining guides ofthe two series respectively, as shown in Fig. 3, passing out of the casing through a transversely extending slot 1 1 formed in the delivery end The warp threads in leaving the casing pass under a rotary guide 15 located in the slot 4 1.. I

The warp threads Z pass from the compartment lO of the casing 10 to the compartment 10 thereof around one of the lower guides, indicated at 43 which is located in the passage 16 formed between the lower edge of the partition 11 and the floor.

Another of the lower series of guides, that which indicated at 43", is positioned in the passage 18 formed between the lower edge of the partition 14 and thefloor. The guide 13 directs the warp Z from the compartment 10 of the drying chamberinto the fresh'air duct or cooling compartment 17.

It will be noted that the adj acentruns of warp threads extending between the upper and lower guides are not parallel to each other but are disposed at a slightangle with respect to each other, thus the air currents "by a link 63 and one end while they move in a general direction subsubjected to currents of air passing them at right angles to their length.

Each of the warp guides is made in the form of an open, perforated or slatted cylinder, for the purpose of reducing air resistanoe as much as possible. Each guide comprises a shaft 50 on which are secured heads 51,51 adapted to receive theoppositc ends respectivelyof a'series of rods or tubes 52, The warp threads rest on these rods. or slats 52 between the heads 51, 51 of the cylinders. V i

The shafts 50 of theupper and lower series of guides are rotatably mounted in bearings 55 supportedby and secured to longitudinally extending beams 56 which are suitably secured to the frame of the casin The guides ll and 45 located at the receiving and delivery ends of the casing are ro-,

tatably mounted in bearings 57 secured to the ends of the casin The dampers 20 and 22 are respectively secured to shafts 58 and 59, which are rotatably mounted in flanged fittings 6O surrounding the inlet and outlet openings 19 and 21 and bearings 61 secured to the top of the casing adjacent one side thereof. On one end of each of the shafts 58 and 59 is secured an arm 62. The arms 62, 62 are connected of this link is con nected to one arm 6 1 of a bell-crank lever, the other arm 65 of which is connected to an operating rod 66. By this means the damp ers 20 and 21 are synchronously operated to control the inlet of fresh air in the same proportion'as the discharge of moist air from the casing. The bell-crank lever 64, 65 is pivoted on a bracket 67 secured to the casing at one end thereof.

From the above description the operation of the drier will be obvious, the warp threads Z upon entering the drying chamber 10 move in a zig-zag path up and down around the upper and lower guides 12 and 13, passing from the compartment 1O to the compartment 10 of the drying chamber under the partition 11. The Zig-xag vertical travel of the warps continues through the compartment 10, from whence the warps travel around the guide 4-3" under the partition 1 L 'unto the fresh air compartment or duct 17.

The air is drawn in an upward vertical dlrection through and from the compartment '10 by the fan 25 and passes horizontally through the coils 15. passes in a heating chamber 12 and heating downward vertical direction From the coils 15 the heated air lBU ' hrough thecompartment-10!, then horizontally through the opening -16, under- 'theparend of the casing where the drying'chamber.

tition 11, to the, compartment 10 'for a repeat iof thecycle; During the circulation of the air as above noted, theair passes through the series'of warp threads'in substantially the'same plane in which the threads are longitudinally disposed, the aircurrents moving ina direction" longitudinally of the threads andat a slight angle relative thereto, due'to the zigzag positioning ofthe threads 1n thecas ngi I During-the circulation oftheiair through the'casing a portion ofthe molst'air 'is ex hausted from thecasing' at the warp-receivthe airis necesmore moist, and at th'ejsame time an equal amount of fresh air is admitted-to the casing'at the warp-delivery end thereof, adjacent the heating coils, wherethe airis practi cally dry. j l i f The warp threads Zleave the compartment l0 at the drier and warmer end thereof and passthrough the fresh air compartment 17 wherein they are cooled beforebeing dis charged from'the casing; 1 In .dryingwarpswhich have been sized it sometimes advisable to set the sizing as the warp threads enter the drying chamber.

In" such cases the receiving cylinder 41 may be replaced bya suitableheated drum, or series of drums,preferably a; hollow drum into which steam is admitted In-passing around the heated drum the-sizing isimmediately set to such an extent that, it Will alhere to thethread and notto thegu-ides and, therefore,'will not-build up on'the guides as the warp passes through the drier. Such 'a'construction as above'noted is illustrated 6, which shows a pair of steam drums 41 and 41 between and around which the wet sized warp threads Z pass when entering guides, partitions, and fan is such that the whole The arrangement of heating coils,

V drier may be constructed as a very compact g of movement apparatus in which the air at no quired to travel any great heating coils which permits the'use of 'rela-' tively small coils requiring less steam for heating the drying air.
